There are many ways to treat acne, including topical medication, oral medication, physical therapy, Chinese herbal medicine, acupuncture, diet, etc. How do you choose? Many people are at a loss.

The treatment plan for acne is not set in stone and should be flexible according to the actual situation of the patient. The principle of individualized treatment should be fully reflected. Grade 1 (mild): Topical treatment is generally used. Topical vitamin A acid preparations] are the best choice. Some [medical skin care products] with the effects of exfoliation, dissolving acne, inhibiting sebum secretion and antibacterial can also be used as an auxiliary treatment method.

Oral [antibiotics] can be used to treat those who are not effective with topical treatment. This type of acne can also be treated with combination therapy, such as oral antibiotics combined with topical [vitamin A acid preparations], or combined application of [red and blue light], [photodynamic therapy], [fruit acid therapy]. Grade 3 (moderate): such patients often need to use combined treatment methods, the most commonly used combined therapy is oral [antibiotics] combined with [topical retinoic acid preparations], and can also be used topically [peroxybenzoyl] at the same time. The application of [hormone therapy] for female patients who require contraception or have other gynecological indications also has good results. Those with poor results can be treated with oral [isotretinoin] alone or with concomitant topical [peroxybenzoyl]. For those who need to apply antibiotics systematically for more than 3 months, the combined application of antibacterial agents such as peroxymethylphenidate that do not cause bacterial resistance is necessary to prevent and reduce the development of drug resistance. Grade 4 (severe): Oral [isotretinoin] is the most effective treatment for this group of patients and can be used as first-line therapy. For those with more inflammatory papules and pustules, a combination of systemic antibiotics combined with [peroxybenzoyl] can also be applied first. After the lesions have improved significantly, the treatment can be switched to oral [isotretinoin] for lesions such as cysts and nodules. Physiotherapy can treat all types of acne. So as long as the economic strip is suitable, you can choose to use it yourself. Regardless of the class of acne. It is very important to maintain treatment once symptoms improve.
